Its headline breaking capacity is 220 kA at 240 V, stepping down to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V — so the available fault current at the installation point must be checked against the voltage-specific rating, not the highest number. The continuous current rating is 25 A from 40 °C through 50 °C, then derates to 24 A at 55–60 °C, and 23 A at 65–70 °C; a panel builder should size the branch circuit for the actual ambient temperature inside the enclosure, not the nominal 25 A.
Integrated accessories and mounting footprint
Dimensions are 70 mm depth, 76.2 mm width, 130 mm height, which fits the standard SENTRON 3VA panel footprint. Maximum power loss is 8.5 W, a figure to include in enclosure thermal calculations.
